Forget about cronuts, donuts, and ramen. A Chicago restaurant just took the crown for the craziest hybrid food yet. For a limited time, Rockit Burger Bar is serving the "MacAttack," which features a beef patty topped with scallions, lettuce, tomato, and Sriracha ketchup sandwiched in between two round slivers of fried macaroni and cheese. We'd heard of mac and cheese being stuffed insideburgers, but this method eliminates the whole pasta-plus-bun double-carb situation. Genius.
